Climate seasonality limits leaf carbon assimilation and wood productivity in tropical forests

The seasonal climate drivers of the carbon cycle in tropical forests remain poorly known, although these forests account for more carbon assimilation and storage than any other terrestrial ecosystem. Based on a unique combination of seasonal pan-tropical data sets from 89 experimental sites (68 include aboveground wood productivity measurements and 35 litter productivity measurements), their associated canopy photosynthetic capacity (enhanced vegetation index, EVI) and climate, we ask how carbon assimilation and aboveground allocation are related to climate seasonality in tropical forests and how they interact in the seasonal carbon cycle. We found that canopy photosynthetic capacity seasonality responds positively to precipitation when rainfall is  < 2000 mm yr⁻¹ (water-limited forests) and to radiation otherwise (light-limited forests). On the other hand, independent of climate limitations, wood productivity and litterfall are driven by seasonal variation in precipitation and evapotranspiration, respectively. Consequently, light-limited forests present an asynchronism between canopy photosynthetic capacity and wood productivity. First-order control by precipitation likely indicates a decrease in tropical forest productivity in a drier climate in water-limited forest, and in current light-limited forest with future rainfall  < 2000 mm yr⁻¹

O artigo analisa a composição das famílias escravas em São José, comarca do rio das Mortes, hoje cidade Tiradentes, entre meados do século XVIII e meados do XIX. A partir de registros de inventários e de casamentos pretende reconstruir a composição das famílias de escravos. A conjugação das informações dessas duas fontes permite constatar a predominância de casamentos exogâmicos entre os cativos de São José, com uma baixa representatividade de casais compostos apenas de nativos.The article analyses the composition of slave families in São José village, in Rio das Mortes county of Minas Gerais captaincy - today Tiradentes - between the middle of the XVIIIth century to the middle of the XXth century. The sources used are inventories and marriage certificates. It indicates that there were the predominance of exogamic marriages among the slaves, with few couples of local natives

Research on slave families in Brazil has aroused from the beginning the usage of serial sources as a way of stressing its relevance to the slave-holding order. Many sources has been exploited in order to check the composition and stability of slave couples. Our intent is to discuss the results from these researches, on the basis of different kinds of sources.Research on slave families in Brazil has aroused from the beginning the usage of serial sources as a way of stressing its relevance to the slave-holding order.

Diversas fontes foram exploradas com a finalidade de observarmos a composição e estabilidade desses laços conjugais formalizados no cativeiro. Nossa intenção é a de discutir os resultados dessas explorações historiográficas, observando a análise comparativa entre as características das informações contidas em fundos documentais tão diversos, a exemplo dos inventários post-mortem, listas censitárias e registros paroquiais de batismos e casamentos
